Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

Indigenous soil and water conservation practices are rarely acknowledged in the design of conventional development projects. Instead, the history of soil and water conservation in Africa has been one of imposing external solutions without regard for local practice. There is a remarkably diverse range of locally developed and adapted technologies for the conservation of water and soil, well suited to their particular site and socio-economic conditions. But such measures have been ignored, and sometimes even overturned, by external solutions. Sustaining the Soil documents farmers' practices, exploring the origins and adaptations carried out by farmers over generations, in response to changing circumstances. Through a comparative analysis of conservation measures - from the humid zones of West Africa to the arid lands of the Sudan, from rock terraces in Morocco to the grass strips of Swaziland - the book explores the various factors that influence adoption and adaptation; farmers' perceptions of conservation needs; and the institutional and policy settings most favorable to more effective land husbandry. For the first time on an Africa-wide scale, this book shows that indigenous techniques work, and are being used successfully to conserve and harvest soil and water. These insights combine to suggest new ways forward for governments and agencies attempting to support sustainable land management in Africa, involving a fusion of traditional and modern approaches, which makes the most of both the new and the old.

Urban agriculture is increasingly considered an important part of creating just and sustainable cities. Yet the benefits that many people attribute to urban agriculture-fresh food, green space, educational opportunities-can mask structural inequities, thereby making political transformation harder to achieve. Beyond the Kale argues that urban agricultural projects focused explicitly on dismantling oppressive systems have the greatest potential to achieve substantive social change. Through in-depth interviews and public forums with prominent urban agriculture activists and supporters-primarily people of color and women, whose strategies have often been underrespresented in the literature Kristin Reynolds and Nevin Cohen illustrate how urban farmers and gardeners not only grow food for their communities but also use their activities and spaces to disrupt the dynamics of power and privilege that perpetuate inequity. Beyond the Kale provides recommendations for these in philanthropy, government, nonprofit organizations, and academia to support such initiatives. Book jacket.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.
